I have a Gazelle and I LOVE it! I bought the $99 Gazelle Edge at Wal-Mart. I love to run, but can't because knee issues. This lets me run with no impact!
Plus, its light enough that I can move it myself wherever I want it. I have even been known to drag it onto the front porch so I can get some fresh air while I "run".
